Hi Pilou,

> On what key press for "Toggle" the Michael Script above, the key of the Shortcut choosen?

Yup, it's whatever key you set the shortcut to be on (the key you put in the left-hand "Key" column for the shortcut).

Then when you push the shortcut one time it will change to that particular lighting style, when you push the same shortcut key a second time it will switch back to the default lighting.
